A method for interchangeably connecting undersea a marine package with first and second pressure control devices. The method includes lowering undersea the marine package toward the first pressure control device such that a first half of a feed-thru component mounted to the marine package contacts a second half of the feed-thru component mounted on the first pressure control device; engaging the first and second halves, wherein the first and second halves of the feed-thru component were not previously engaged while the marine package and the first pressure control device were each assembled above sea; and locking the first half to the second half by using an external pressure such that a functionality of the feed-thru component is achieved.

Interchangeable subsea wellhead devices and methods

A flow regulator includes a flow regulating part configured to receive at an inlet a working fluid at a first pressure and to release the working fluid at an outlet at a second pressure; a slide provided inside the flow regulating part and configured to move along an axis to reduce the pressure of the working fluid; a control part attached to the flow regulating part, the control part including a chamber; a spring housing provided in the chamber and connected to the slide though a shaft, the spring housing configured to move the slide along the axis; a cap provided in the chamber and facing the spring housing, the cap being configured to have plural blind holes; and plural pins extending along the axis and attached to the spring housing, the plural pins being configured to enter the plural blind holes.

Regulator dampening device and method

A lifting device configured to lift a bonnet of a blowout preventer. The lifting device includes two or more lifting pins, each lifting pin including, a body having an elongated shape and configured to enter through a hole in the bonnet; a shoulder connected to the body and having an external diameter larger than an external diameter of the body; and two or more threaded regions at different locations on the body and configured to receive threaded screws, each threaded region being formed in the body such that a coordinate of the threaded region in a given inertial system is substantially identical to a coordinate of a center of gravity of a corresponding bonnet in the same given inertial system when the lifting pin is inserted into a hole of the corresponding bonnet.

Lifting device and method for lifting a bonnet

A method for connecting a lower marine riser package to a lower blowout preventer stack. The method includes lowering a frame of the lower marine riser package toward a frame of the lower blowout preventer stack such that a first half of a feed-thru component contacts a second half of the feed-thru component; floating at least one of the first half of the feed-thru component or the second half of the feed-thru component while the frame of the lower marine package is further lowered toward the frame of the lower blowout preventer stack; and engaging the first half of the feed-thru component to the second half of the feed-thru component after further lowering the lower marine riser package toward the lower blowout preventer stack.

A method to interchangeably connect a plurality of Lower Marine Riser Packages with a lower BOP stack includes engaging a Lower Marine Riser Package connector of the Lower Marine Riser Package, with a Lower Stack mandrel connector of a Lower Stack, thereby aligning the Lower Marine Riser Package and the Lower Stack axially about a vertical axis, engaging at least one ring alignment pin of the Lower Marine Riser Package with at least one alignment plate of the Lower Stack, thereby rotationally aligning the Lower Marine Riser Package and the Lower Stack within a specified angle about the vertical axis, and engaging feed-thru connections between the Lower Marine Riser Package and the Lower Stack.
